While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed:

What is claimed is:

1. The combination with a vehicle having an opening in its rear panel, of a bullet proof sign mounted in said opening, a movable panel for covering said opening to conceal the sign and means operable from the drivers seat to control the movements of the panel.

2. The combination with a vehicle having an opening in its rear panel, of a bullet proof sign mounted in said opening, a movable panel for covering said opening to conceal the sign, means for illuminating the sign and means operable from the drivers seat to control the movements of the panel.

3. The combination with a vehicle having an opening in its rear panel, a bullet proof sign in said opening, a movable panel for closing the opening to conceal the sign, a housing remote from the sign and panel, means in the housing for cotrolling the opening and closing of the panel, a cover for said housing and means tolock the cover to said housing.

4. The combination with a vehicle theft signal, of a housing for inclosing the controlling means for said signal, a cover plate for said housing, a pair of locking bolts carried by the cover plate and adapted to engage the housing to prevent removal of the cover plate and key actuated means locking said bolts.

5. In a device of the class described, a housing, a hollow cover plate for said housing, said cover plate and housing having diametrically opposed slots therein, a pair of locking bolts adapted to be projected through said slots, heads on the inner ends of said bolts, ayielding plate beneath the heads, said heads having notches therein, pins on the plate for projecting through the notches to hold the bolts in locked position, a key having a shank adapted to be projected through the heads on thebolts, and lugs on the key shank for engaging the ins to force them out of the notches where y the bolts will be free to swing about the key shank and be withdrawn.
